Brain Chemistry
Low dopamine levels make people less likely to work toward achieving a goal.
People with clinical depression often have increased levels of monoamine oxidase A (MAO-A),
- an enzyme that breaks down key neurotransmitters,
- resulting in very low levels of
- serotonin,
- dopamine,
- norepine.
Genetics
A British research team isolated a gene that appears to be prevalent in multiple family members with depression.
The chromosome 3p25-26 was found in more than 800 families with recurrent depression. Scientists believe that as many as 40 percent of those with depression can trace it to a genetic link.
